The scientific name for the process of water purification by plants is phytoremediation. This natural method leverages the capabilities of plants to absorb, accumulate, and detoxify pollutants from soil and water. Various plant species can be used to remediate different types of contaminants, including heavy metals and organic pollutants. Phytoremediation is a cost-effective and environmentally friendly solution that enhances ecosystem health while restoring contaminated ecosystems.
